本文考虑了辐射传递方程的矩量法，它已被发展并使用不同的方法进行了研究。出现的问题，这个时刻系统的边值问题，使用麦克斯韦型边界条件进行说明。一种新的方法的基础上考虑的积极和消极的半通量的开发和示出，以克服上述问题。此外，给出了新的力矩系统的数值格式和数值结果。
In this paper a moment method for radiative transfer equations is considered which has been developed and investigated using different approaches. Problems appearing for this moment system for boundary value problems using Maxwell-type boundary conditions are described. A new method based on the consideration of positive and negative half fluxes is developed and shown to overcome the above problems. Moreover, a numerical scheme and numerical results for the new moment system are presented.
